Just replace all the occurrences related to one of the proposed date code by the one you want.

Then, check the changes in the widget configuration and it should work!

For instance :

– Open wordpress-popular-posts.php;
– Search all the occurrences related to one of the date codes: for example “m/d/Y”;
– Then, replace them with the desired date format;
– Activate the date in the configuration and enjoy!

It wasn’t really necessary to modify the plugin’s code for that. If you’re using the wpp shortcode or the wpp_get_mostpopular template tag then you can use the stats_date_format parameter to pass your own date format.

Funny thing is that this cannot be done with the widget, probably forgot to add this to it at some point. I’ll add this to the widget so the date format can be also changed there as well.
